Magnetic Field of a Helmholtz Coil

Application ID: 15

A Helmholtz coil is a parallel pair of identical circular coils spaced one radius apart and wound so that the current flows through both coils in the same direction. This winding results in a uniform magnetic field between the coils with the primary component parallel to the axes of the two coils.

Applications of Helmholtz coils range from canceling the earth’s magnetic field to generating magnetic fields for experiments and applications requiring such. Helmholtz field generation can be static, time-varying DC or AC, depending on the applications.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product\'s capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
